P0031.1 product shows a site/species' molar fraction, for the given air mass classification (by wind origin). Top plot shows the molar fraction of continental or marine air mass (hourly means, CCGCRV smooth curve and CCGCRV trend curve) as well as hourly means of all other air mass origin. Bottom plot shows the molar fraction's growth rate for continental or marine air mass, as well as the growth rate of all air mass origins.
- Data used: hourly means, continuous time series, site and species as listed in title.
- Y-axis: top plot: Species molar fraction ; bottom plot: growth rate (calculated from NOAA's CCGCRV script).
- Timeframe: all available data, i.e. time frame with both classification and air data.
